THE BEST TREES TO PLANT 75 



tricts it grows freely, and there forms a dense, 

 healthy dark green mass. From this it must 

 not, however, be inferred that the Yew cannot 

 survive in smoky towns, for it grows freely 

 wherever it is not subjected to an inordinate 

 amount of atmospheric impurities. Soil of 

 fairly good quality should be used when 

 planting the Yew, particularly where the sur- 

 roundings are unfavourable. 



THE HORSE CHESTNUT (JEsculus Hippo- 

 castanum) and the English Elm (Ulmus cam- 

 pest r is) may be seen in a fairly satisfactory 

 way in many town parks, but only where they 

 are not exposed to smoke and soot to any 

 great extent. In confined spaces both these 

 trees soon show signs of distress, the points 

 of the branches gradually becoming unhealthy 

 and the trees ultimately dying off prematurely. 

 Taking everything into consideration, neither 

 of these trees can be recommended for plant- 

 ing in smoky districts, though in the more 

 open parts, as in Hyde or Regent's Park, 

 they last for a long time and attain to good 

 old age.
